technical field

The subject matter disclosed herein relates generally to macro images, and in particular to methods of obtaining such images using multi-cameras (eg, dual-cameras).

Background technique

Multi-aperture digital cameras (or multi-cameras) are standard in mobile electronic devices (eg, smartphones, tablets, etc.). Multiple cameras typically include a camera with a wide field-of-view (or angle) FOV _W (a wide-angle camera), and at least one additional camera with the same field-of-view (eg, a depth assist camera), with a larger Narrow (wider than wide) field of view FOV _T (Telephoto or Tele camera), or ultra-wide (UW) FOV _UW with wider than wide field of view. In some embodiments below, a wide-angle or ultra-wide-angle camera may be referred to as a non-Macro camera.

Macro photography mode is becoming a popular differentiator for smartphone cameras. Macro photography refers to shooting an object very close to the camera so that the image sensor records the size of the image of the object almost as large as the actual size of the object being shot, i.e. it has a large object, such as an image magnification of 10:1 to 1: 1. Such images may be referred to as macro images. The first smartphones to include a macro camera (usually based on an ultra-wide-angle camera) with a macro field of view FOV _M have entered the consumer market. A macro camera can be implemented with a tele camera (Tele camera). One advantage is the high magnification of macro images captured with a telephoto camera, so it can be said to be a “Super Macro Image”. In some examples, the macro camera may be a scanning telephoto camera. camera), which can scan a scene using its native macro field of view, such as described in commonly owned US Patent 10,578,948.

Macro images are recorded at an object-camera distance of about 20 cm or less. Ultra-wide cameras may still be able to focus to these small distances. Typically, very small objects (eg, less than 1 cm in size) are located as image objects (ie, objects of interest (OOI)). Such a very small object of interest for macro images may be obscured by a multi-camera hosting device, making it difficult for a macro camera to capture the object of interest in an accurate manner. This is especially important when the macro field of view captures a small area of the object (eg, a few square millimeters) (eg, placed 2 cm to 10 cm from the camera) while being integrated in a larger setup. It would be beneficial to have a method that supports a fast and user-friendly way to point the macro camera's macro field of view at very small objects of interest.

SUMMARY OF THE INVENTION

In some embodiments, a split screen view is provided on a multi-camera hosting device showing a preview image segment of the ultra-wide camera field of view (FOV) and A preview image segment of the Macro field of view (FOV _M ) to support targeting objects of interest (OOI) using the macro field of view.

The image segment of the ultra-wide camera's field of view shown to the user can contain distinguishing elements that mark the area of the object of interest that will be captured by macro mode.

Detailed ways

Embodiments disclosed herein address the problem of occlusion of an object of interest when performing macro photography using multiple cameras included in smartphones and other mobile electronic devices. For simplicity and as an example only, this solution is illustrated with a dual-camera, but it should be understood that it is also clearly applicable to multi-cameras with three or more cameras.

FIG. 1 shows a typical field of-view (FOV) scale for a smartphone 100, including multiple cameras (not shown), including an ultra-wide (UW) camera with coverage over most of the an ultra-wide field of view (FOV _UW ) 102 of the scene; and a macro camera with a macro field of view (FOV _M ) 104 covering a small portion of the scene. Example sizes and ratios between ultra-wide and macro output images can be seen.

In some examples, the macro camera may be a continuous tele zoom camera (continuous tele zoom camera), where the macro field of view varies with the zoom factor (ZF).

FIG. 2A illustrates an embodiment of a smartphone, numbered 200, according to the presently disclosed subject matter, the smartphone comprising: an ultra-wide camera with an ultra-wide field of view 202; a macro camera with a macro field of view 204 ; and a screen (display) 206. A system description of the smartphone 200 is given in FIG. 5 . As indicated by the four arrows in FIGS. 2A-2C , the smartphone 200 can be moved by the user in four or more directions to manually move the macro field of view toward an object of interest (OOI) /region-of-interest (ROI). Screen 206 shows an example of a first screen for displaying images from multiple cameras. Macro photography involves capturing small objects up close. The macro camera may include a telephoto (Tele) lens with a focal length much larger (eg, 3x to 25x) than that of the ultra-wide-angle camera. In this case, ultra-wide-angle cameras can easily focus to close distances (e.g., 2 centimeters (cm) to 30cm), but have poor spatial resolution due to their small focal length and large field of view. For example, consider an ultra-wide-angle camera with a 2.5 millimeter (mm) focal length and a macro camera with a 25mm focal length. The two cameras may include the same or different sensors (eg, have the same or different pixel counts and pixel sizes). Assume that both cameras include the same sensor, eg, with an active image sensor width of 4mm. When focusing to 5cm, the M of the macro camera is 1:1 and will capture objects 4mm wide (the same width as the sensor). The ultra-wide-angle camera has an M ratio of 19:1 and will capture objects up to 76mm wide.

In some examples, a smartphone, such as smartphone 200, may include a wide-angle camera in place of or in addition to an ultra-wide-angle camera having an ultra-wide-angle field of view 202 in order to perform the methods disclosed herein. W) A wide field of view (FOV _W ) (not shown) of the camera is smaller than the ultra wide field of view 202, but still larger than the macro field of view. In some examples, the wide-angle camera may not be able to focus on objects that are very close, eg, 10cm. In such an example, to perform the methods disclosed herein, the wide-angle camera may be focused to its minimum focal length, eg, 20 cm.

The aforementioned ultra-wide or wide-angle cameras have a greater depth of field than macro-capable telephoto cameras with a macro field of view. Regions of interest are easier to detect in ultra-wide or wide-angle image data than in macro image data. Therefore, ultra-wide-angle, wide-angle or macro camera image data can be used to automatically detect and select regions of interest.

In an exemplary case, the user wishes to use smartphone 200 to capture an object of interest (eg, flower 208 forming image 216 in the camera) or a region of interest with very high (macro) resolution. For the method of use disclosed herein, the screen 206 is divided into two parts, a first part 210 (possibly cropped) and a second part 212 . The first screen portion may display first image data from the first camera using a first field of view (FOV ₁ ), and the second screen portion may display second image data from the second camera using a macro field of view . The example here shows a split screen view on the screen, ie two screen parts are displayed side by side. In other examples (not shown), a "picture-in-picture" view may be displayed on the screen, ie one screen portion may be displayed as an inlay in another screen portion. In some examples, the second screen portion may be displayed on the entire screen or a large portion of the screen, except for the portion where the first screen portion is displayed, wherein the first screen portion covers a smaller area of the screen than the second screen. In the embodiment of Figures 2A-2C, the two screen parts typically have a "landscape" orientation, ie the first screen part and the second screen part are vertically split, which is beneficial when the device is fixed in a landscape orientation of. Screen 206 may include known additional icons or symbols (not shown). The first screen portion 210 displays a cropped ultra-wide field of view (hence may be referred to as an "ultra wide angle (UW) screen portion 210"), while the second screen portion 212 displays a macro field of view (hence may be referred to as a "macro screen"). section 212"). Within the first portion 210, the macro field of view 204 may be marked by a physical (ie, visible on screen) rectangle 204'. The rectangle 204 ′ represents the actual position of the macro field of view 204 relative to the ultra-wide field of view 202 . Optionally, another physical rectangle 204" indicates an ultra wide angle preview of the object of interest (flower) 208 in order to guide the user towards the flower 208. The user can always see the FOVM 204 relative to the rectangle 204" in the ultra wide angle screen portion 210 At the same time, the macro screen portion 212 displays the scene within the FOVM. In use, the user moves the smartphone with the camera towards the flower 208 . In the macro screen portion 212, an arrow 218 indicates the direction and distance of movement required to align the flower 208 with the macro field of view 204. In some examples, image data from the ultra-wide field of view 202 may be displayed in the macro screen portion 212 . This is beneficial, for example, when the macro camera may not be in focus of the entire camera macro field of view 204 or when there are other optical or image quality issues.

2B, 2C illustrate the process of moving the smartphone (and macro field of view) toward the flower 208 (ie, toward the preview 216). As shown in Figure 2B, the ultra-wide screen portion indicates the movement of the macro field of view 204, making it close to the rectangle 204" (preview 216). Flowers begin to appear in the macro screen portion 212. In Figure 2C, the macro field of view 204 is seen as a fully overlapping rectangle 204" in the ultra-wide screen portion, while the flower 208 is fully displayed in the macro screen portion 212.

FIG. 3 illustrates an embodiment of a smartphone, labeled Micro 300 , according to the presently disclosed subject matter, the smartphone comprising: an ultra-wide camera with an ultra-wide field of view 302 ; a macro camera with a macro field of view 304 ; and a screen 306. The screen 306 is divided into an ultra-wide-angle screen portion 310 and a macro screen portion 312, both of which are in portrait orientation, i.e. the first screen portion and the second screen portion are split horizontally, which is beneficial when the device is held in portrait orientation . In Figure 2C, within the first portion 310, the macro field of view 304 is marked by a physical rectangle 304', and optionally another physical rectangle 304" indicates an ultra-wide preview of the flower 308 (which forms an image 316 in the camera) ) to guide the user towards the flower 308.

This method or device for splitting the screen and displaying the super wide-angle field of view and the macro field of view at the same time allows the user to find the object of interest and capture it with the macro camera (and the super-wide-angle camera can also be used at the same time), even if the mobile phone (image capture device) occludes the object of interest.

FIG. 4 shows a flowchart of a method for macro photography using split screen in a mobile electronic device according to embodiments disclosed herein. In step 400, a screen of a mobile electronic device is segmented to simultaneously display a non-macro (eg, ultra-wide angle) camera image stream (steam) (or a cropped version thereof) and a macro camera image stream (or a cropped version thereof). . At step 402, an object of interest/region of interest is selected in the ultra-wide field of view of the ultra-wide camera by a dedicated algorithm running on the object of interest/region of interest selector 546 or by a human user A scene as a macro image. The ultra-wide field of view as well as the macro field of view have been calibrated. As is known in the art, the position of an object/region of interest in the ultra-wide field of view can be converted to the position of a corresponding object/region of interest in the macro field of view. In step 404, each position of the object of interest/region of interest relative to the macro field of view is calculated based on the positioning positions of the object of interest/region of interest in the super wide-angle field of view. At step 406, the user is visually or otherwise directed toward the location of the object/region of interest relative to the location of the macro field of view. Visual or other indications for guidance may be visual (eg, by arrow 218 shown in Figures 2A-2B), or by dedicated sounds, or by some tactile feedback. In some examples, user control unit 544 is configured to provide visual or other indications. Following the instructions of step 406, the user moves the camera's hosting device (eg, smartphone) until the object/region of interest appears in the macro field of view. In step 408, the user captures a macro image (also referred to as a Super Macro image) of the object/region of interest.

5 schematically illustrates an embodiment of an electronic device (eg, a smartphone), numbered 500, that includes multiple cameras and is configured to perform the methods disclosed herein. The electronic device 500 includes a macro camera 510 having a macro field of view. The macro camera 510 includes a macro lens module 512 having a macro lens, a macro image sensor 514 , and a lens actuator 516 for actuating the macro lens module 512 . The macro lens forms a macro image recorded by the macro image sensor 514 .

Alternatively, the macro lens may have a fixed effective focal length (EFL) that provides a fixed zoom factor, or an adaptable (variable) lens that provides an adaptable zoom factor. Fixed effective focal length. The adaptation of the fixed effective focal length may be discrete or continuous, ie a discrete number of variable fixed effective focal lengths for providing a plurality of discrete or continuous zoom states with corresponding zoom factors. Camera 510 can automatically switch to a beneficial zoom state.

Alternatively, the macro camera 510 may be a folding camera including an optical path folding element (OPFE) 518 and an optical path folding element actuator 522 for actuating the optical path folding element 518 for optical image stabilization (optical image stabilization, OIS) and/or field scanning. In some embodiments, field-of-view scanning of the macro camera may be performed by activating one or more optical path folding elements. For example, commonly owned US Provisional Patent Application No. 63/110,057, filed on November 5, 2020, describes a scanning macro camera that performs field-of-view scanning by driving two optical path folding elements.

The macro camera module 510 further includes a first memory 524, for example, in an electronically erasable programmable read-only memory (EEPROM). In some embodiments, the first calibration data may be stored in memory 524 . In other embodiments, the first calibration data may be stored in a third memory 560 such as Non-Volatile Memory (NVM). The first calibration data may include calibration data between image sensors 514 and 534 .

The electronic device 500 also includes an ultra-wide-angle camera 530 having an ultra-wide-angle field of view that is larger than the macro field of view of the camera 510 . The ultra-wide-angle camera 530 includes an ultra-wide-angle lens module 532 having an ultra-wide-angle lens and an ultra-wide-angle image sensor 534 . Lens actuator 536 may move lens module 532 for focusing and/or optical image stabilization. In some embodiments, the second calibration data may be stored in the second memory 538 . In other embodiments, the second calibration data may be stored in the third memory 560 . The second calibration data may include calibration data between image sensors 514 and 534 .

Macro cameras may have, for example, an effective focal length of 8 to 30 mm or more, a diagonal field of view of 10 to 40 degrees, and an f-number of about f/#=1.8 to 6. Ultra wide angle cameras may have, for example, an effective focal length of 2.5 to 8 mm, a diagonal field of view of 50 to 130 degrees, and an f/# of about 1.0 to 2.5.

In some embodiments, the macro camera may cover approximately 50% of the area of the ultra-wide camera's field of view. In some embodiments, the macro camera may cover about 10% or less of the area of the ultra-wide camera's field of view.

The electronic device 500 further includes an application processor (AP) 540 . The application processor 540 includes a camera controller 542 , a user control unit 544 , an object of interest/region of interest selector 546 , and an image processor 548 . The electronic device 500 also includes a screen control 550 and a screen 570 . Screen 570 may display methods as disclosed herein.

Returning now to the method of use in FIG. 4, in some examples, the camera controller 542 may use the ultra-wide or wide-angle camera image data to automatically change the state of the macro camera (ie, control changes in the scan state of the macro camera). The state may be a scan (or steer) state, a zoom state or a focus state. For example, ultra-wide or wide-angle camera image data can be used to automatically steer (or scan) the macro field of view of the scanning telephoto camera toward an area of interest (change in scan state of the macro camera). In one example, the macro camera may be self-steering, and the step 406 of directing the macro field of view to the area of interest may be done automatically by the camera controller 542 . As mentioned above, selecting the object/region of interest in the ultra-wide field of view as the scene of the macro image camera can be accomplished by a dedicated algorithm running on the object/region of interest selector 546 . In another example, a macro camera can use ultra-wide or wide-angle image data to switch between zoom states. The camera controller 542 may automatically switch the macro camera to a beneficial zoom state (ie, control a change in the zoom state of the macro camera), eg, when steps 404 and 406 are performed. A beneficial zoom state may be one in which the macro object of interest or the region of interest fully enters the macro field of view. In yet another example, the camera controller 542 may use image data from the wide-angle or ultra-wide-angle camera to automatically focus the macro camera to a region of interest within the macro field of view (ie, control changes in the focus state of the macro camera) . Objects of interest or regions of interest spanning a segment of the scene larger than the macro field of view may be fully captured in two or more consecutive frames, where each frame includes an different fragments. The sequential frames together include image data on the object of interest or region of interest as a whole, and are stitched into a single image by the image processor 548 .
